“Possible and partial sustainability” in economical, physical and social terms in a defined context is related to maximum quality of life with a minimum of natural resources exploitation. It is evident that current tools to analyze social reality are insufficient. In the case of quality of life the approach is mainly quantitative under the basis of well-being indexes combination to establish thresholds and make comparisons in country regions and among countries. This research work deepens in architecture as a means of achieving habitability and well-being for users of public urban spaces and indoor spaces. The work intends to explore the relationship between habitability parameters and well-being expectations in buildings and public urban spaces. Studying technological features in buildings would make us understand design tools, technologies involved so as to elaborate trends in planning. Urban and architectonic habitat implies movements, repetitive behaviours in time, which give permanence. Nevertheless, there exist multiple expressions of temporalspaces, which not only include permanence but also identity, territoriality, temporality and mainly materiality as a social production. Habitability is a function of comfort parameters concerning the object of architecture. Well-being is a resultant of comfort parameters, ecological services, and cultural perceptions concerning public spaces. The term “habitability” is presented to evaluate quantitative and qualitative features of architectonic design whereas “well-being” considered as an index of quality of life in a social context. People use parks or courtyards mainly due to habitability conditions beyond cultural issues, that is to say, temporal and spatial satisfaction given by comfort conditions. In Rosario city, Argentina, with a temperate-humid climate, public parks form part of the net generated by Indian Law present leaf foliage canopy granting habitability conditions. In the same way, interior “patios” of Italian and Spanish immigrants’ houses as well as comfortable conditions in rational Modern Architecture express environmental sensibility. In all of this, the comfort conditions are achieved by passive systems and conscious design. Case studies are presented to introduce this approach as a means of exploring possible sustainability in a defined context and social reality: Rosario city.
